Builds are not architecture universal

MacOS 26.3
BaseLib 0.0.4

When running the released builds on macOS, the game fails to load the BaseLib DLL:

[INFO] Loading assembly DLL BaseLib.dll
[ERROR] Error loading mod BaseLib.pck: System.IO.FileLoadException: Could not load file or assembly '/Users/jamesboyko/Library/Application Support/Steam/steamapps/common/Slay the Spire 2/SlayTheSpire2.app/Contents/MacOS/mods/BaseLib.dll'. The assembly architecture is not compatible with the current process architecture.
File name: '/Users/jamesboyko/Library/Application Support/Steam/steamapps/common/Slay the Spire 2/SlayTheSpire2.app/Contents/MacOS/mods/BaseLib.dll'
   at System.Runtime.Loader.AssemblyLoadContext.LoadFromAssemblyPath(String assemblyPath)

This is fixed by building against the sts2.dll in data_sts2_macos_arm64, but there may be a way to decouple it from different architectures at all.

Top, built on my machine: msil
Bottom, from latest github release: x86

Notably, this does not happen when building my own mod against the x86 sts2.dll

Found the cause of this; when I build using "Build" it uses msil as it's set to do, but if I Publish the dotnet publish run by godot produces an x64 dll

For now, I'm just checking the dll type before uploading.
